Way to small. You would have to pully down so far that the RPM's on the S/C would be up in the self destruct range, or live with a small amount of boost. 1500 refers to the CC displacement per revolution, and even on the 4.6 engines the 1700 (1.7L) blower is maxing out around 11 PSI / 18000 RPM blower speed, if memory serves me correctly.
Of course, thats just my opinion, I could be wrong...
